Features The DBE08 is a stand-alone Dolby E encoder. Although it is not a complete replacement for the DP571 from Dolby Laboratories, it can be considered as a functional equivalent. The advantages however are the facts that the DBE08 is modular, can run on a dual power supply, Ethernet and SNMP compatible, and has a nice enhancement to the menu structure. This last item is an interesting feature. The DBE08 can handle 8 presets with metadata (A through H) and 10 presets of different program combinations. The often used program combinations like 5.1+2 are available with 4 times the individual metadata sets. This will result in the possibility to have 4 times the program combination 5.1+2, but with 8 different metadata settings.

Stand alone Dolby E encoder Fully compatible with Audio ADD-ON bus 20 bit mode for 8 channels, 16 bit mode for 6 channels encoding 4 presets 5.1+2 (with 8 different metadata sets) 4 presets 2+2 (with 8 different metadata sets) 2 presets 2+2+2+2 (with 8 different metadata sets) Metadata settings for: Program text (16 character text) Dialog level Bit-stream identification Dynamic range (film, music, speech, etc.)

RF mode Dynamic range (11 dB more sensitive) Center downmix level Surround downmix level Dolby surround Preferred downmix Lt/Rt Center and Surround downmix level Lo/Ro Center and Surround downmix level Surround-EX flag DC filter LFE filter Low-pass filter Surround 3dB attenuation Surround phase shift Input channel swapping (any channel to any encoder input) Individual gain and phase adjustment per mono channel Individual delay offset adjustment (0 to 1300 ms) Built-in generator One selectable AES/EBU bypass input with additional delay settings Locks to Black & Burst or Mastercard
